Trinity (135 mm high) vs Trinityᵐ (60 mm high)
Geometric accuracy in machine tools is essential for maintaining part quality, minimizing scrap and reducing downtime. In multi-axis machining, even small deviations in linear or rotary movements can significantly affect process capability.
Our Position and Rotary Inspector and Analyzer series integrate the Trinity and Trinityᵐ wireless probes for linear and rotary axis measurement. These patented systems enable simultaneous non-contact X, Y and Z measurements with high speed and accuracy.
Machine tool qualification in real-time
Trinity and Trinityᵐ are particularly suited for routine machine verification in high-precision manufacturing environments. With measurement done in under a minute, it enables daily or weekly checks or before critical production runs, ensuring that the machine remains within specification. It is equally valuable after maintenance work, such as spindle replacement or axis adjustment, where confirmation of accuracy is required before returning the machine to service. Over time, data collected can also be used for predictive maintenance, detecting trends that indicate wear or control issues before they result in failure. Their wireless design, measurement precision and portability enable efficient integration into manufacturing environments where accuracy and uptime are critical. These measuring systems serve as reliable components in predictive maintenance procedures, supporting both cost efficiency and production consistency.

Measurement principle
The Trinity or Trinityᵐ probe is mounted in the spindle, while a calibrated masterball or linear array is placed on the table. As the spindle follows a programmed path, the probe (representing the Tool Centre Point) tracks its position relative to the reference. This setup captures real-time positional deviations across multiple axes. Operators can immediately visualize errors such as pivot misalignment, squareness issues and linear deviations. The system also detects dynamic instability, incorrect controller settings and bearing wear. Measurement uncertainty is below 1 μm, enabling use in demanding applications.

New design and performance
The new compact Trinityᵐ is designed for small-machine environments where both precision and footprint are critical. It measures 60 mm in length, weighs 325 g and offers a 2 mm range with 0.2 μm resolution at a 2 kHz sampling rate. Battery life supports up to 13 hours of continuous operation or 100 days in sleep mode and can be recharged via a wireless charging station. Communication is handled through Bluetooth 5.0 and the system has an optional integration for an emergency stop function.
Trinityᵐ can be integrated into the toolchain for automatic access.
Trinity vs Trinityᵐ
For larger machines or those requiring an extended measurement range, the Trinity probe variant may be the better choice. Trinity offers a range of 3.5 mm and Wi-Fi connectivity, making it more suitable for large-scale applications.
Due to its reduced footprint, the new Trinityᵐ probe is suitable for smaller machines where space is limited. It offers improved measurement accuracy (export controlled) and an extended battery life achieved through power-saving technology. For additional operational safety, an optional emergency stop (E-stop) feature is available.
